Tactics for dealing with really fast bombadiers?

I keep running into enemies that use bombadiers that are super fast. And I mean fast. I can barely get up and run before getting rained on. It happens more in summit that anywhere else.

Obviously with a lot of enemies you can't always identify them quickly, and sometimes they can hit you a few times before you find them. So what tactics do you guys use to defend against them?

Right now they are bugging me more than the RC lawnmovers.

EDIT: I meant the drone bombadiers that carpet bomb.
